i am currently breast feeding but trying to switch over to formula. i have given my 3 week old 2 oz of powdered formula and she does ok until about an hour to 2 hours later when she wakes up out of her sleep choking on thick saliva and unable to breathe. i have to pat her back to get it out and use the bulb syringe to suck it out. what would cause this? it doesn t happen when she gets strickly breast milk , only some spit up

Exclusive breast feeding till 6 months of age is the best for your baby.

Formula milk especially when given through a bottle is very easy for the baby to suckle than from breast. So chances of overfeeding are more. And when babies are not burped properly after the feed it adds to the problem.
In infants the sphincter between food pipe and stomach is lax due to which reflux happens commonly due to which the contents from stomach come up.

Choking can be life threatening.
To avoid such risks
- Do not overfeed
- Burp properly after each feeds
- Do not put the baby to cot immediately after feeding. Wait for a minimum of 30 min to 45 min by keeping him erect.
- Do not rock the baby after feeds
- Left lateral position (baby`s left hand side down on the floor) will be helpful in preventing aspirations. You may also raise the upper end of the baby by placing a folded towel beneath his shoulder blades.
- Do not leave the baby unattended even when he is asleep.
- If the problem continues, please do not hesitate to visit your Pediatrician- he might need medications to prevent reflux.
